Because Drumagog is a real-time plugin, there is a delay associated with using it. When using Simple triggering mode, the delay can be as small as 1 or 2 ms (not enough to notice in most cases). However, using the more sophisticated Advanced Triggering Mode introduces as much as 50ms of delay. If your host supports plugin delay compensation, you're in luck - everything is adjusted for you. However, not all hosts support this feature, and you might need to manually nudge or move your audio track back by the amout Drumagog tells you on the main page. Drumagog's Live triggering mode has zero latency (at a cost of less accurate dynamic triggering).
